They had a strange kettle on top of a kettle, sort of rims mash and boil combination rig. Put half the brewing liquor in the top pot, half in the bottom, heat the bottom, continuously pump from the bottom to the top while draining from the top to the bottom. When strike temp is set, add malt to the top and mash while recirculating for an hour. You end up with wort ready to boil in the bottom kettle.
I can’t see how this would be terribly efficient, but he said seventy-something percent.
John was at the LHBS for Big Brew. He said that sales to nanos has increased, and the new products had that in mind. Homebrewers are still the core business.
The price of the RIMS Rocket was there. It was in tiny print on the display card.
I’m a little worried about the RIMS Rocket since the velocity through the chamber will be very slow. I suppose that the concern with wort overheating may be reduced if the watt density is super low. But I prefer the smaller diameter RIMS tubes from an engineering viewpoint since the wort velocity will be much higher than in the RIMS Rocket. I suppose that they might have incorporated some other features or controls to avoid over-heating the wort, but I’m concerned.
